Hi all. I'm trying to build a Docker container where I am installing tools that I need and modifying the

PATH

in the

Dockerfile

. Looks something like this:

# Dockerfile

...
RUN git clone <https://github.com/asdf-vm/asdf.git> /root/.asdf --branch v0.10.0
ENV PATH=/root/.asdf/shims:/root/.asdf/bin:$PATH

COPY .tool-versions ./.tool-versions
RUN asdf plugin-add python && \
	asdf plugin-add nodejs && \
	asdf plugin-add yarn && \
	asdf install python && \
	asdf install nodejs && \
	asdf install yarn
...
RUN yarn run gulp compile
...

So I'm setting the

/root/.asdf/bin

path to be part of the

PATH

for the Dockerfile, but when the line

RUN yarn run gulp compile

executes in the

docker_image

target, I get the following error:

Traceback (most recent call last):
  File "/pants/setup/bootstrap-Linux-x86_64/2.13.0rc0+git30af7f9c_py38/lib/python3.8/site-packages/pants/engine/process.py", line 272, in fallible_to_exec_result_or_raise
    raise ProcessExecutionFailure(
pants.engine.process.ProcessExecutionFailure: Process 'Searching for `python3` on PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/runner/.local/bin' failed with exit code 127.

python3

can't be found and

PATH

is missing

/root/.asdf/bin

. I can't tell if that's the

PATH

from my local host or if that's inside the container but I know that on my local I have:

[python-bootstrap]
# All pants users should configure asdf for 3.8.
search_path = [
    "<ASDF_LOCAL>",
]

in my

pants.toml

, so pants should know to check for asdf locally, and I've set the

PATH

in the context of the container build. I'm not sure what my next steps are and I'd appreciate any help!

pants.engine.process.ProcessExecutionFailure: Process 'Searching for `python3` on PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/runner/.local/bin' failed with exit code 127.

is an error from pants, not docker
